Rapid prenatal diagnosis of trisomy 21 by real-time quantitative polymerase chain reaction with amplification of small tandem repeats and S100B in chromosome 21.
Trisomy 21 (Down syndrome) is the most common congenital anomaly, and it occurs in one out of 700-1000 births. Current techniques such as amniocentesis and chorionic villi sampling (CVS) require lengthy laboratory culture procedures and high costs. This study was undertaken to establish a rapid prenatal diagnosis of trisomy 21 using real-time quantitative polymerase chain reaction (PCR) of fetal DNA from amniotic fluid. ⋯ The difference between these two groups was statistically significant (p-values were 0.0379 and 0.0379, respectively). Prenatal diagnosis of trisomy 21 by real-time quantitative PCR using STR (small tandem repeats) amplification of D21S167 and S100B is a useful, accurate and rapid diagnostic method. Furthermore, it may also be useful for prenatal diagnosis with fetal DNA from maternal blood, and for preimplantation genetic diagnosis and prenatal counseling.

Comparative StudyA comparison of different pelvic reconstruction surgeries using mesh for pelvic organ prolapse patients.
This study was carried out in order to compare the effects in different surgeries using mesh in pelvic organ prolapse patients whose leading points were C. Thirty-nine patients were categorized into 3 groups: group A pelvic reconstruction with hysterectomy; group B hysterectomy prior to pelvic reconstruction; and group C pelvic reconstruction with uterus preserved. At first visit, POP-Q stage was determined, and age, BMI, admission days, operation time, post-operative stage and complications were observed and results were analyzed and compared. ⋯ Pelvic reconstruction using mesh is a highly efficient method of treating pelvic organ prolapse. Improvements in stage and post-operative complications were not significantly different in the groups. However, uteropexy showed a shorter operation time, fewer admission days, and less erosion due to mesh than conventional pelvic reconstruction with hysterectomy.

Development of a clinical protocol for home hospice care for Koreans.
As the Korean government's recognition of the importance of hospice service grows, the government has initiated a variety of hospice services in Korea. Each hospice organization has shown a significant difference in its health care delivery methods, constitution and care content. Developing a clinical protocol is essential for establishing standardized hospice services. ⋯ Eighteen health problems and a total of 223 interventions (173 major treatments and nursing interventions, and 50 optional interventions) were included in the final clinical protocol. This study is expected to contribute to the overall qualitative improvement of home hospice care and the subsequent shortening of documentation time. Evaluation tools and a regulatory feedback system need to be developed in order to maintain consistent evaluation procedures based on the continuous promotion and use of the protocol.

Perioperative anticoagulation in patients with mechanical heart valves undergoing elective surgery: results of a survey conducted among Korean physicians.
The optimal perioperative anticoagulation management in patients on warfarin therapy is poorly defined due to the lack of randomized trials. Because guidelines are heterogeneous, it was hypothesized that "treatment strategies are not uniform in clinical practice". Between February 2003 and May 2003, a questionnaire with 4 different clinical scenarios was distributed to physicians by e-mail, or direct contact was made by a survey monitor. ⋯ Outpatient, full- dose, subcutaneous UH or low-molecular-weight heparin (LMWH) was the most selected option in the postoperative phase for all scenarios, with the exception of number 4 (52.9% in scenario 1, 34% in scenario 2, 32%, in scenario 3 and 28% in scenario 4). Even among expert clinicians, the management of perioperative anticoagulation is heterogeneous. In particular, the definition of risk categories and the optimal intensity of antithrombotic drugs need to be defined by well-designed prospective studies.

Surgical treatments for lumbar disc disease in adolescent patients; chemonucleolysis / microsurgical discectomy/ PLIF with cages.
The herniated lumbar disc (HLD) in adolescent patients is characterized by typical discogenic pain that originates from a soft herniated disc. It is frequently related to back trauma, and sometimes it is also combined with a degenerative process and a bony spur such as posterior Schmorl's node. Chemonucleolysis is an excellent minimally invasive treatment having these criteria: leg pain rather than back pain, severe limitation on the straight leg raising test (SLRT), and soft disc protrusion on computed tomography (CT). ⋯ Among these cases, we performed chemonucleolysis in 65 cases, microsurgical discectomy in 94 cases, and posterior lumbar interbody fusion (PLIF) with cages in 33 cases including 7 reoperation cases. The clinical success rate was 91% for chemonucleolysis, 95% for microsurgical disectomy, and 89% for PLIF with cages, and there were no non- union cases for the PLIF patients with cages. In adolescent HLD, chemonucleolysis was the 1st choice of treatment because the soft adolescent HLD was effectively treated with chemonucleolysis, especially when the patient satisfied the chemonucleolysis indications.
